SPECIFICATION forming part of Letters Patent No. 483,880, dated October4, 1892.

Application iiletl December 31, 1891. Serial No. 416,633. (No model.)

To all whom, it may concern:

Be it known that I, WILLIAM J. TUEPIN, a citizen of the United States,and a resident of Oakdale Station, in the county of Allegheny and Stateof Pennsylvania, have invented certain new and useful Improvements inStove- Mats; and I do declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same, referencebeing had to the accompanying drawings, and to letters of referencemarked thereon, which form a part of this specification.

Figure l of the drawings is a perspective detail view showing themetallic ring. Fig. 2 is a plan view of the mat, and Fig. 3 is a centralsection on linea: 00.

This invention has relation to certain new and useful improvements instove-mats; and it consists in the novel construction and combination ofparts, as hereinafter specified. i

In the accompanying drawings the letter A designates a disk ofasbestus-board of sufficient thickness to possess a considerable degreeof rigidity and inclosed at its marginal and peripheral Vportions in ametallic ringbinding B. This binding comprises a strip of metal whichhas rst been bent into a ring approximately-V-shaped in cross-section..In order to form this met-al strip into a ring of this shape, it is runbetween a pair of corrugated rolls or dies, which are so constructed asto leave the edge or angle of the ring with a plain surface, at thesametime transversely corrugating the lateral edges of the strip, as shown.These corrugations not only serve to take up the surplus metal producedby the operation of bending and enable a perfect ring to be formed whichcould otherwise not be done, but they also serve to increase theetticiency of the mat, inasmuch as they render the binding stronger andalso serve to prevent the mat from slipping when in use. After the ringis thus formed,its ends being left free, the asbestus disk is insertedthe-rein and by the aid of a press or other suitable means the sideportions are bent toward each other to clamp said disk, the ends of thering being slightly overlapped and secured by a single rivet. By the useof this corrugated ring I do away with the necessity of employing twoconcentric annular plates, one on either side of the marginal edge ofthe disk, and between which the disk is held and secured by aseries ofrivets. A binder formed of a single piece of metal also serves to betterprotect the circumferential edge of the disk.

O designates a diametrical brace or stiiener of metal and held in placeby having its ends clamped between the disk and binder. This brace,however, may sometimes be omitted.` A handle is also usually providedcomprising a clasp D,having its arms d turned under between the disk andthe edge of the binder. In the loop formed by these arms is loosely helda ring E.

The device is placed on a stove either with or without the ordinarymetallic lid, and forms a mat on which a disk or other cooking utensilis placed. The asbestus disk serves to prevent any substance which isbeing cooked-such as sirups, jellies, porridge, and oatmeal-fromsticking yto and burning on the bottom, and thereby avoids the necessityfor constant stirring ordinarily required. This is a peculiar feature ofasbestus which, in so far as I am aware, is not possessed by any othersubstance. However highly heated it may become, the article being cookedin the.

vessel supported thereon, although receiving sufficient heat to cause itto cook fully, will not adhere to the bottom of the vessel, as iscommonly the case with the articles above named or others.

I am aware that it is not broadly new to inclose a disk of incombustiblematerial in a WILLIAM I. TURPIN.
